Phone Conference with Jeff Hawke - NETL
September 29, 2010 - 1:30 PM
Literature search incomplete - AD700 project, turbine operation at 700C
Life expectancy of turbine components: 250,000 hours, about 30 years
Materials Selection Criteria:
Creep - Larson Miller Parameter: tested at 100 MPa for 100,000 hours at operation T
Developed technology
Manufacturing ability
Moving components = forged. ex. HP rotor; 80K lb casting and 40-42 in diameter - not possible with Ni based alloy
Stationary component = cast. Can't air cast Ni, can't cast >100 kg.
Inspectability for defects minimum detectable flaw identification using ultrasonic.
Tensile strength --> yield strength
Impact strength (steel) or fracture toughness (nickel based)
Patent licensing - only supplied by 1 company, $ and capability issues
Fatigue - thermal, low cycle (casting, big components)
Physical properties - thermal expansion (pieces in contact need to match), thermal conductivity, modulus, poisson's ratio
Weldable - everything is welded, so can't use gas turbine materials (low life expectancy). Important for crack removal - grind down and weld overlay.
Next Steps:
Learn Classes of Ni Alloys, composition, strengthening phase (science direct, patents)
617 - solid solution strengthened - lacks high yield strength
718 - Ni super alloy - particle strengthened, high yield, not usable for high T
Nimonic 105 - particle strengthened, better than 718
Look up data sheets for properties
Haynes
Nimonic
Carpenter
Special Metals
Ni @ 700C typically a composite bc $
gamma prime strengthened materials more expensive than solid solution
Possible - composite rotor:
Beginning (1400F) -weld- Middle (1200F) -weld- End (1000F)
Meeting with Robert Heard
September 20, 2010 - 1:30PM
If we can't get numbers, we should make educated guesses
Look at the improvement of the materials over years and extrapolate the data
Meeting with Chris Roberts
September 20, 2010 - 2:00PM
Casing is a static property
creep/oxidation/fatigue/cost/welding are important factors
bolts are external, welding of sections of rotor together and you can change materials throughout

Professor will contact Morgantown NETL about a visit

Meeting with Robert Heard
September 15, 2:00 pm
Start to look at this project from a business point of view Cartech supplies the materials to turbine companies Sell the most material you can
Focus in on what Cartech wants. What materials are going to make the most impact/money What are they shooting for? Focus on one place where we can make a change They want to focus on one area where they can make a difference
Come up with a methodology for the decision making (performance index, etc.) Designing a methodology for the selection of a turbine material
Meeting with Chris Roberts
September 15, 2:30 pm
Define property requirements for materials within the turbine High pressure, medium pressure, low pressure sections For each section of turbine, which properties are most important
Cartech could focus on discs and blades Casing, may or may not be of interest
NETL, EPRI, Oakridge
Look for AUSC! just USC is not always the right operating conditions Immature technology. 10-15 years down the road
The group decided to use Celsius and mpa 760C=1400F

Phone Conference with Pete Rozelle from DOE
September 9, 2010 - 10:30AM
Research Recommendations:
1) Understand fundamentals of turbines
2) Understand fundamentals of steam conditions
3) Rationale behind design of 1950s power plants, particularly Eddystone Plant
4) Newest technology and state of the art research on ultra supercritical coal power plants
Resources:
DOE website
ASME publications
American Power Conference proceedings
Meeting with Robert Heard
September 7, 2010 - 2:00PM
Goal of project? Coal power plants. To make more efficient, operate at higher temperatures, need better materials. Leaning towards turbines. Should choose based on what company needs Experimentation? Collect data from other sources (can’t do test ourselves) Need to develop some sort of analysis to put data to the test—validation method Decision tree or something WBS will change as the project progresses Put timetables on tasks when we talk to Chris
Meeting with Sridhar Seetheraman
September 7, 2010 - 2:30PM Meeting
Project summary Turbine vs Boiler Turbine Critical aspect—is there a material that costs too much or doesn’t work? Would we want to look at what is being done or what could be done in the future (especially for economic analysis)? Is there a material that could work? NETL contacts? Has a turbines project in Pittsburgh—Seetharaman will arrange DOE turbine headquarters contact as well Efficiency saves money and carbon emission What would the carbon tax have to be to make it worth it? Use environmental economics to solve Corrosion issues: chromium or aluminum alloys or adding a coating
General Group Meeting
September 6, 2010 - 1:30PM
Discussion of boiler vs turbine:
boiler information is harder to find while turbine structure, information, and data are well defined
can more easily find size, weight, material prices for turbine components
industry reps are more willing to talk about turbines
Our project will have one focus, however in the end we want do an economic analysis of replacing material for the entire plant. This will require us to look at the boiler even though we have chosen to focus on the turbine. This type of analysis will require us to make assumptions about the boiler and all other aspects of the plant.
Power plant visit:
NETL - operates out of Pittsburgh, Morgantown, and Albany
Siemens - natural gas turbines
Contact: Paul Ohodnicki about local plant visit (NETL)
Ideal visit when the plant is shut down so we can see the boiler
Have questions ready for representative (what materials they do/do not like to work with, welding, etc.)
Economic Analysis Model:
Initial cost of remodeling power plant plus lifetime costs need to be considered
Lifetime considerations: runtime (days/year), emission reductions after remodel
What is expected for next meeting:
All: literature bibliographies by Wednesday
Kelly: email Paul Ohodnicki about plant visit
All: be ready to discuss WBS with Prof. Heard and Prof. Seetheraman on Wednesday
General Group Meeting

Finish reading all documents and summarize them on the wiki by Wednesday
Conference Call with Chris Roberts
September 2, 2010 - 1:30PM Schedule Specifics
Meeting on Monday with Chris in person to discuss gantt chart and WBS
Will do research and choose direction of project by this meeting
Setup weekly conference call times with Chris set at 2:30PM on Wednesdays
Project Specifics For the past 15 years there has been great amount of research into power generation as infastructure of old plants may fail as demand for power continues to increase Some plants have been around for 50+ years and are in need of upgrading to get more out of the fuels being used.
subcritical -60's
supercritical - late 70's
advanced ultra-super critical - now - need for materials to withstand 1400F and 35MPa
Look at components for boiler section and account for heat generation, also can look at steam turbines which do the electricity generation put on the grid Project is generally Boiler vs Turbine - we choose the dierction Boiler would entail conditions outside of the pipe vs inside of the pipe, by products of combustion, and coatings hot zones, etc. - more challenging What are the property requirements? find materials to meet these requirements. Support with experimental data/research What is the cost of these new materials/alloys? best properties vs lowest cost
WBS and gantt chart: project is an open literature project - we need to have structure and order to what we research contact companies for oxidation and mechanical data of alloys
In the end we would like to recommend a material with economics considered or propose new novel techniques
General Group Meeting
September 1, 2010 - 4:00PM
Schedule Specifics
Contact Chris for alloy specific side of project
Set up weekly meetings at 1:30PM on Wednesdays with faculty advisor
Project Specifics
Generally as you increase operating temperature of power plans, you increase efficiencyCO2 emissions is very important - look at tax, economic factors as these are big concerns todayLook into alternative fuels being used such as oxyfuel which combusts with pure oxygen so that separation of nitrogen after the fact is not necessary
operating temps must be able to go up to 1700 from ~1400 for this to happen and the materials now simply cannot take this heat
steam can also have corrosive effects
Find materials or composites (metals with ceramics?) that may be able to withstand these difficultiesLook into thermal barrier coatings to help protect from heatMaybe do a life cycle analysisLook into State of the Art technology and look at advantages and disadvantages of this technology
